3. If the system file damage caused by abnormal shutdown is serious, then you can reinstall the system to solve it completely.

4. If the hardware contact is abnormal, plug and unplug the memory and graphics card, and wipe the gold finger with an eraser.

5. If the motherboard BIOS is abnormal, unplug the power cord, cut off the motherboard button battery, wait for three minutes, and then reinstall the motherboard.

6. If the hardware is damaged, it can only be sent for repair, and the problem can be solved after the hardware is replaced by professionals.

Reasons why it won't turn on and the screen goes black: system problems and hardware problems.

1. System problems.

Solution: Resolve the problem by restoring the system or reinstalling the system.

The laptop comes with a system recovery method:

1. Press the power button to turn on the machine, and press the F9 button continuously after the logo appears;

2. During the Windows recovery process, the system will automatically load the recovery file, or select Windows Setup and press the Enter key;

Second, hardware problems.

Solution: After-sales inspection and maintenance.

You can use a USB flash drive to make a 360 first aid disk, use the 360 first aid disk to start the computer, and use it to reinstall the system.

If the computer is poisoned, you can go to a computer shop to fix it.

If the hardware fails, take it to a repair shop.

It's not a virus, it's still the legendary black screen.

Please check the cooling system inside the case, the CPU overheating causing a protective forced shutdown of the computer is a common cause of the situation you encounter.

The CPU temperature is too high, change to a good heatsink.

Hello, I'm glad to answer for you, I hope it will be helpful to you.

There are many reasons for the black screen, one is caused by a virus, try the whole antivirus, the second is a system problem, or there is a conflict between software and hardware, and the system can be solved by reinstalling the system, and the third is a problem with the graphics card, the graphics card driver is wrong or the graphics card is broken or the graphics card is loose.

Clean up the dust under the chassis, wipe off the gold finger of the graphics card with a skin like skin, and see if it is magnetized, 4 hardware problems, for example.

Memory module CPU

Graphics card motherboard.

and so on, whether there is looseness.

5 Monitor Issues.

The monitor is broken.

6. The hardware acceleration is set too high and exceeds the frequency range.

Click Windows Start Menu - Control Panel - Double-click the Show --- Troubleshooter tab, and under Hardware Acceleration, gradually drag the slider from Full to a position close to None-click the OK button.

The 7BIOS settings are incorrect or the overclocking is unsuccessful.

Caused by a black screen.

It is possible to reset the BIOS settings to their default values by discharging the motherboard.

8. The screen is black when the program is opened, for example, the game, one is that the graphics card does not meet the requirements of the game and is black, and the other is that it conflicts with the program, so it is black and crashes.

9 hit Microsoft's black-screen plan.

It is recommended to reinstall the system.

Plagiarism must be reported--- thank you for adopting--- I wish you happiness and health.

There are many reasons why a computer has a black screen, and the common ones are:

Shows poor contact of the data cable;

There is no power supply to the motherboard;

Poor graphics card contact or;

Poor CPU contact and overheating;

Poor contact of memory modules;

poor power performance;

Machine infection. CIH virus, BIOS

is destructively refreshed.

Microsoft black screen, please patch.

Most of these problems are the relationship between the memory and the graphics card, loose or poor contact, just move it or use the eraser to wipe the gold finger of the interface

There is too much garbage in the system disk "C", there are too many add-ons to boot the machine, the virtual memory is too low, and it will get stuck if there are too many things loaded.

Redo the system, you can do it yourself for each system disk, and it will be good for a while.

Def, though

The things on the disk are gone, and it's best to pay some money to go to the computer maintenance department to do it, and the important things will be kept.

If you can back it up yourself, it will save you the trouble to do it yourself.

The computer restarts the black screen, it is recommended to check the following aspects:

1. Whether the power supply is insufficient, change to a higher power to see if the problem can be solved.

2. Whether the memory module is in poor contact or has a problem, you can use another memory module to start from the new one.

3. Whether the CPU heat dissipation is normal, see if the silicone is aging, or there is a problem with the fan.

1.Software or viruses can sometimes be caused, the solution is to reinstall the system, if the reinstalled system still restarts the computer, you have to find it from the following hardware.

2.The grid voltage is unstable, the grid is flashing, and the voltage regulator is added.

3.The power supply of the computer is not stable, replace the power supply.

4.The computer motherboard is not good, the power supply is insufficient, check if there is a capacitor bulge on the motherboard, and the top is flat when the capacitor is normal.

If the fan doesn't spin, or the speed is too slow, or the gap between the heatsink is blocked by dust, causing the CPU to overheat and restart, you can feel whether the temperature of the heatsink is too hot.

6.Other hardware on the computer is faulty, resulting in insufficient power supply on the motherboard, and you need to replace it.

That's all you can think of, I hope it helps you.

Obviously a CPU issue, open the case. Look at whether the wind of the CPU fan is strong or not, and whether the wind is hot or not. Air heat, dismantle the fan, and put some new heat dissipation silicone on the CPU (available in the computer store of the Electronic City, ** up to 5 yuan a bottle.)

Don't be cheated). If the wind of the fan is small, change the fan, properly.

Check whether it is poisoned first, and it should be killed; Secondly, look at the hardware, whether there is a problem with the fan.
